2.) coding TV Tuner with your software
3.) turn ignition totally off (eject car key)
... waiting 10 seconds ...
4.) turn ignition on again (position II)
5.) unplug TV Tuner (blue connector)
If I ONLY turn off the ignition or ONLY unplug the TV Tuner after coding, the coding does not work. (neither enabling nor disabling "TV in motion" funktion).
If I don't unplug the TV Tuner after ignition off->on, a click on "Read TV settings" shows me the correct status I coded, but it does not work like coded.
Does anyone have an idea why I also have to unplug the TV Tuner (so completely disconnect from power)

You did not wait long enough for the car to power down. Like the nav, the video module switches on and off according to the ibus traffic. 10 seconds is not long enough for the car to have gone to sleep.
As an indication, the red LED on the nav shows when there is ibus traffic - when the red LED on the nav goes out, then the ibus is in a sleep state and all connected devices have shut down.
Then after 15min, the entire car goes to sleep - light on transmission goes off - this is the full power-down for the vehicle.
